I love crumble topping anything and when paired with big juicy blueberries, I can’t resist. Even better when it’s a fast, easy, no-mixer, flexible recipe.  The sweet, juicy blueberries contrast perfectly with the crispy and crumbly oatmeal topping. I much prefer this to blueberry pie because there’s no crust to make and roll out. Instead, there’s a crumble topping, which trumps pie crust every day of the week. I skipped the whipped cream and ice cream this time, but I’ve no doubt the blueberry oatmeal crisp would be amazing a la mode.

ALL OF MY BLUEBERRY RECIPES!  In the fridge: Cover with plastic wrap and chill for up to 5 days. As time passes, the crispness of the crispy topping will diminish and it will become softer. This is just the nature of a crisp and there’s nothing you can do about it. In the freezer: Cover tightly or transfer to an airtight freezer container. Freeze for up to 3 months. When ready to eat, thaw overnight in the fridge. The oatmeal topping will not retain crispiness after you thaw it and the texture will change. Tried this recipe? Leave a review!
